What Mo's Engineers Do During a Boiler Service

A proper boiler service is more than a quick look. Here is what we check, test and clean on every visit.

  1. 1
    Visual inspection for leaks and corrosion

    Check the boiler casing, pipework connections and components for visible leaks, rust or corrosion.

  2. 2
    Remove boiler casing

    The front panel comes off so we can inspect internal components directly.

  3. 3
    Clean the burner

    Burner debris and sooting reduces combustion efficiency. We clean it to restore proper flame quality.

  4. 4
    Inspect and clean the heat exchanger

    The heat exchanger is the most critical internal component. We check for cracking, scaling and sooting.

  5. 5
    Check and clean the spark electrodes

    Worn or dirty electrodes cause ignition problems. We clean and set gap correctly.

  6. 6
    Combustion analysis

    We measure the flue gases with a calibrated analyser. This confirms the boiler is burning gas correctly and efficiently.

  7. 7
    Flue integrity check

    We test the flue is clear of blockages and properly sealed. A leaking flue is a carbon monoxide risk.

  8. 8
    Gas pressure test

    We check the gas inlet pressure meets the manufacturer specification for your boiler model.

  9. 9
    Safety device checks

    We test the pressure relief valve, overheat thermostat and any other safety cut-outs.

  10. 10
    Carbon monoxide check

    We test for CO in the flue gases and at the boiler casing.

  11. 11
    System pressure and controls check

    We confirm the system pressure is correct and test the programmer, room thermostat and any zone controls.

  12. 12
    Benchmark book service record

    We complete the manufacturer service record (benchmark book) which documents the service details and is required for warranty claims.

If we find a fault during the service we explain it clearly and give you a quote before any repair work starts. You get a copy of everything we record.

How Long Does a Boiler Service Take?

Honest answer based on what we actually see in Glasgow properties.

Standard service, well-maintained boiler

45 to 60 minutes. A boiler that has been serviced regularly and is in good condition is a straightforward visit.

Older boiler or first service in a while

60 to 90 minutes. More thorough cleaning needed and more careful inspection of components showing age. We take the time needed.

Boiler with a fault found during service

Add time for diagnosis and discussion. We stop, explain what we have found and give you a quote. No work starts without your agreement.

We give you a realistic time estimate when you book. We do not rush a boiler service.

Why You Should Service Your Boiler Every Year

Three good reasons. None of them are just to make money for heating engineers.

Your manufacturer warranty requires it

Worcester Bosch, Vaillant, Baxi, Ideal and every other major brand require annual servicing by a Gas Safe registered engineer to keep the manufacturer warranty valid. Miss a service and you may find the warranty void when you need it most. We complete the benchmark record that proves the service was done.

It prevents expensive breakdowns

Most of the boiler faults we repair in Glasgow are preventable. Dirty burners, scaling on heat exchangers, worn seals that become full failures. A service catches these at the small-problem stage when they are cheap to address, not at the breakdown stage when they leave you without heat on a January night.

Carbon monoxide safety

A boiler that is not burning correctly produces carbon monoxide. CO has no smell. A service includes flue gas analysis and a CO check. We find problems with combustion that would never be visible from outside the boiler. This is not a scare tactic. It is the most important thing we do on a service visit.

What Happens If You Skip the Annual Service?

The honest version. Not a lecture.

Risk
Your warranty may become void

Most boiler manufacturers state clearly that annual Gas Safe servicing is required to maintain the warranty. If you skip it and the boiler develops a fault, the manufacturer may refuse the warranty claim. A 10-year warranty on a Worcester Bosch is only worth 10 years if you service it every year.

Risk
Small problems become big ones

Dirt on the burner reduces efficiency. Scaling on the heat exchanger builds up. A small seal that weeps becomes a full leak. These faults develop slowly and are caught at a service. Left unchecked they become complete boiler failures at the worst possible time.

Risk
Your boiler uses more gas

A dirty, poorly maintained boiler has to work harder to produce the same heat. This increases gas consumption and your energy bills. A clean, well-maintained boiler is a more efficient boiler.

Risk
Carbon monoxide risk increases

Combustion faults that develop gradually can produce CO at levels that are dangerous over time. Annual flue gas analysis is the check that catches this. It is not detectable any other way.

We are not trying to scare you into booking. We are telling you what we see in Glasgow properties when people call us for a repair. A lot of it is preventable.

When Is the Best Time to Book a Boiler Service in Glasgow?

September and October. Every year.

Why Autumn

Your boiler works hardest from November to March. Servicing it in September or October means it goes into winter clean, tuned and certified. Any faults found are fixed before you need it most. Availability is also better in autumn than in winter when engineers are busier.

Why Not Winter

Every heating engineer in Glasgow is busier from November to February. Booking slots are harder to find. The boiler most likely to fail is the one that has not been serviced. If it breaks down in January you are calling for an emergency repair, not a routine service. Book in autumn and avoid that situation entirely.

Not autumn? Still book it. An out-of-season service is far better than no service at all. Call 07988 591331 any time.

Landlords, Combine Your Boiler Service and CP12 in One Visit

Two legal requirements, one engineer, one visit.

If you rent out a Glasgow property you need an annual gas safety certificate (CP12) and your boiler needs an annual service to keep the manufacturer warranty valid. Both jobs are done by a Gas Safe engineer. Both take around an hour. We carry them out in the same visit, saving you time and reducing the total cost compared to two separate appointments. Call 07988 591331 and book a combined service and CP12 when you make the appointment.

Annual Boiler Service

Gas Safe engineer inspects, cleans and tests the boiler. Benchmark record completed. Warranty maintained.

Gas Safety Certificate CP12

Legal landlord requirement. All gas appliances inspected. Certificate issued same day.

Our radiator pipe was bent and leaking. They answered straight away… Guy was here an hour later and he was wearing ID, very professional, patient and kind. We just got a new carpet in this room and he done an amazing job on getting little to no water on it. Couldn't recommend enough, price was reasonable.

We lost heating just in time for the coldest day of the year with a baby in the house… When I contacted them they were ready to dispatch that night. Fixed by the afternoon. Quoted that morning and no extra charges were added. Honestly cannot thank them enough.

As a small business owner, I needed a drainage company that could respond quickly. The team attended first thing in the morning, cleared the blocked drain and carried out a full CCTV survey. All documentation emailed across promptly. Professional, efficient and great value for money.
